1988 – The Royal Commission on the Historical Monuments of England surveyed and measured the milecastle. 1999 – The milecastle was excavated by P Duffy of Central Archaeological Services as part of an interim evaluation carried out by English Heritage's Centre for Archaeology. Two trenches were put in to assess the state of the milecastle. The east and west walls were uncovered as well as some flagstone surfacing on the west side and an oven in the south-east corner. The remains were found to have been "considerably damaged by ploughing". 2000 – An archaeological investigation was carried out on the vallum near to Milecastle 10 by English Heritage in September. Associated turrets Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 10 are known as Turret 10A and Turret 10B. Turret 10A Turret 10A (Throckley East) is located west of Milecastle 10. The turret lies beneath the modern Hexham Road (B6528) and there are no visible surface remains but has been excavated in 1930 and 1980. The 1930 excavation could only examine the south-east corner of the turret. It discovered that the walls were approximately thick and stood five courses of stone high. The entrance to the turret was in the south wall. The 1980 excavation, carried out before some nearby construction work, was more extensive and discovered just two distinct occupation layers within the turret. Most of the pottery discovered in the turret has been dated to before 140 AD with just one sherd dating later than that. This places the turret's occupation to within the early period of the wall's life with little later activity, though there is no evidence that the turret was demolished after it ceased to be occupied. The excavation discovered that the walls consisted of a core of sandstone and clay surrounded by pointed mortar, with foundations of stone slabs set on clay. Extensive areas of burning and charcoal were discovered within the turret which could represent a series of hearths in the door threshold and along the north wall. Other finds on the site have included a spearhead and four worked flints and a possible platform in the south west corner. The 1980 excavation removed the floor
